Abstract :
In this letter, we present a module-type Viterbi decoder (VD) which is a combination of module operation and VD at the receiver. We describe design rules by which the module-type VD and the conventional VD have the same functionality regardless of the shape of the folded-module area or the constellation. The module-type VD in conjunction with the Tomlinson-Harashima precoder at the transmitter reduces the system complexity significantly as compared to a conventional VD.
